This 15th century shrine is the burial place of Shah (Sheikh) Ala ai-Din Mohammad, a reverend Sufi who lived and preached in Esfahan in the 15th century. He was granted special favor by Sultan Mohammad ibn Baysonqor, a Timurid governor of Fars and Iraq. The story goes that, after the revolt of Sultan Mohammad against his uncle Shahrokh Mirza, he flew to Lorestan. When Shahrokh took Esfahan, he vented his anger on Mohammad's supporters, among them Sheikh Ala al-Din. Sufi was first exiled to Saveh, but soon Shahrokh, at the behest of his wife Gowhar Shad, had him executed. The legend says that Sheikh damned Shahrokh from his gibbet, and Shahrokh died less than eighty days after Shah Ala al-Din, either accidentally or otherwise. After the death of his uncle, Sultan Mohammad transferred the Sheikh's body to Esfahan and buried him with highest honors in the precinct of the khaneqah, where Sheikh taught during his lifetime. The Sheikh's descendants were later also buried in the mausoleum, but their gravestones have disappeared, and their names are forgotten.
The original structure of the mausoleum dates from 1422-1447, but it was renovated under the Safavids. Inside the shrine, an inscription dated 1604 is indicative of the modifications of the site made during the reign of Shah Abbas I. The mausoleum's ornamentation is very remarkable. One of the inscriptions in the building is performed in plaster
by Seyed Mahmud Naqqash, who is also responsible for the magnificent lettering on the
door of Be it al-Sheta prayer hall in the Congregational Mosque. A handsome stucco Nastaliq inscription in verse on green background is shaped in the form of a vase and can be read bottom-up. Recently, the building has been considerably repaired. The superbly carved wooden door of the sanctuary is a modern replica, but the craftsmen largely adhered to the original design.
